In the old days you could use expanding foam to separate the boot area (where the fuel tank in my car is situated) from the drivers compartment.
It was used to seal the openings over the rear wheel arches.

Can anyone tell me if this is still the case?
I'm taking my car to the scrutineering session on the 28th at Knockhill and I'd like to have as much done in advance

Yeah the normal non fire resistant stuff gives off horrendous noxious fumes and would be absolutely the last thing you would want in a car in the event of a fire._________________Motorsport Exige Project Thread

Go to your local builders merchant and you will get Fire Retardant (intumescent) foam. If you can fabricate a full firewall, or simply enclose the fuel tank in a sealed box, that may be a neater option._________________Renny
